Oligo(quinoline-2,3-diyl)s having a terminal bromo group were synthesized by the Suzuki–Miyaura coupling of 5,8-disubstituted 2-bromoquinolin-3-ylboronic acid derivatives, and their helical structures were elucidated by a single-crystal X-ray analysis of the hexamer, UV measurements, and induction of a non-racemic helical sense by introduction of a chiral end group.
通过 5,8-二取代 2-溴喹啉-3-基硼酸衍生物的 Suzuki-Miyaura 偶联合成了具有末端溴基的寡聚(喹啉-2,3-二基),并通过单-六聚体的晶体 X 射线分析、UV 测量以及通过引入手性端基诱导非外消旋螺旋。
